Explore our primary array of high-precision electronic equipment, industrial laser components, and advanced solid-state lighting products engineered to international standards.
In the era of hyper-scale datacenters, autonomous LiDAR vehicle guidance, and gigahertz fiber-optic communications, the photodiode is no longer just a passive light-sensing component. It has evolved into a critical bandwidth enabler.
A High-Speed Photodiode converts modulated optical signals into equivalent high-frequency electrical signals with minimum distortion. For global tier-1 procurement teams, finding a reliable OEM and ODM supplier capable of manufacturing photodiodes that combine high quantum efficiency with ultra-low junction capacitance is paramount. We focus on the design, optimization, and packaging of semiconductor detection architectures to meet demanding response times in the nanosecond and picosecond range.
To ensure high fidelity at high bandwidths, our manufacturing processes prioritize three major performance parameters:

Choosing the right photodiode architecture depends heavily on your system's operating wavelength, speed, and signal constraints. We offer extensive custom OEM configurations:
Ideal for 300nm to 1100nm spectrum range. Features low dark current and high stability. Highly suitable for UV-to-visible applications, high-precision industrial scanners, and medical analytics.
Engineered for the 800nm to 1700nm NIR spectrum. Perfect for high-speed fiber communications, eye-safe 1550nm LiDAR, and spectroscopy requiring outstanding quantum efficiency.
We supply traditional PIN photodiodes for high linearity and moderate speed, as well as Avalanche Photodiodes (APD) offering internal gain for ultra-low-light and rangefinder applications.
| Material / Type | Spectral Range (nm) | Peak Wavelength (nm) | Rise/Fall Time (Typ) | Active Area Diameter | Typical Applications |
|---|---|---|---|---|---|
| High Speed Si PIN | 350 - 1100 | 900 | 0.5 ns (V_R = 10V) | 0.5 mm | Barcode Scanners, Optical Data links |
| InGaAs High-Speed PIN | 800 - 1700 | 1550 | 0.1 ns (V_R = 5V) | 0.1 mm | 10G/40G Fiber Optic Receivers |
| Silicon APD (Avalanche) | 400 - 1100 | 800 | 0.3 ns (M = 100) | 0.2 mm | Laser Range Finders, 905nm LiDAR |
| Custom Coaxial / Pigtailed | 800 - 1650 | 1310/1550 | < 50 ps (High Speed) | 50 um | Telecom Optical Time Domain Reflectometer (OTDR) |
From defense aerospace to commercial cosmetic hardware, high-speed photodiode technology forms the foundational layer of precision detection equipment.
Modern LiDAR systems rely heavily on photodiodes with rapid rise times to calculate Time-of-Flight (ToF) distance mapping. Custom OEM suppliers must guarantee tight dimensional tolerances, customized chip layouts, and environmental stability under automotive AEC-Q101 testing standards.
In medical-grade dermatological devices—such as Painless Titanium Permanent Laser Hair Removal Machines and triple diode laser setups (755nm, 808nm, 1064nm)—high-speed photodiodes are utilized inside the optical feedback loops. These loops monitor pulse duration and energy outputs in real-time, preventing energy spikes and guaranteeing safety and efficiency during treatments.
High-reliability components integrated with Android Digital Screen Touch TV Power Supply Units and optical signal interfaces rely on optoelectronic couplers to isolate high voltages. Fast response phototransistors and photodiodes prevent feedback lag and screen flickering in heavy-duty commercial equipment.
Modern networks require photodetectors to support transceivers running at 25G, 100G, or 400G configurations. Our sub-mount chip designs and ceramic carrier packages allow seamless chip-on-board (COB) wire bonding inside high-density transceivers.
